Google har offentliggjort et \u00e5bent s\u00e6t af biblioteker og v\u00e6rkt\u00f8jer til implementering af et system for fuld homomorf kryptering, der g\u00f8r det muligt at behandle data i krypteret form, uden at de forekommer \u00e5benlyst i nogen af beregningens faser. V\u00e6rkt\u00f8jet giver mulighed for at skabe programmer til fortrolige beregninger, der kan arbejde med data uden dekryptering, herunder udf\u00f8re matematiske og enkle strengoperationer p\u00e5 krypterede data. Projektkoden er skrevet i C++ og distribueres under Apache 2.0-licensen. <\/p>\n

I mods\u00e6tning til ende-til-ende kryptering, giver homomorf kryptering ud over beskyttelsen af dataoverf\u00f8rsel mulighed for at behandle data uden dekryptering. Med fuld homomorfi forst\u00e5s muligheden for at udf\u00f8re operationer med addition og multiplikation af krypterede data, hvorfra man kan udf\u00f8re enhver vilk\u00e5rlig beregning. Udgangen er et krypteret resultat, der ville svare til krypteringen af resultatet af lignende operationer p\u00e5 de oprindelige data. <\/p>\n

Arbejdet med data ved homomorf kryptering g\u00e5r ud p\u00e5, at brugeren krypterer dataene og uden at afsl\u00f8re n\u00f8glerne sender dem til behandling i en ekstern tjeneste. Denne tjeneste udf\u00f8rer de \u00f8nskede beregninger og genererer et krypteret resultat, uden at den har mulighed for at bestemme, hvilke data den faktisk arbejder med. Brugeren dekrypterer de udleverede data ved hj\u00e6lp af sine n\u00f8gler og modtager resultatet i \u00e5ben form.

Af anvendelsesomr\u00e5derne for homomorf kryptering n\u00e6vnes oprettelsen af cloud-tjenester til fortrolige beregninger, implementering af elektroniske afstemningssystemer, oprettelse af anonymiserede routingprotokoller og behandling af foresp\u00f8rgsler p\u00e5 krypterede data i DBMS, samt fortrolig tr\u00e6ning af maskinl\u00e6ringssystemer. <\/p>\n

For eksempel vil homomorfisk kryptering v\u00e6re nyttig i medicinske applikationer, der kan modtage fortrolige oplysninger fra patienter i krypteret form og give sundhedspersonale mulighed for at udf\u00f8re analyser og identificere afvigelser uden at skulle dekryptere. Homomorfisk kryptering kan ogs\u00e5 hj\u00e6lpe med at udf\u00f8re forskning, der unders\u00f8ger forholdet mellem sygdomme og bestemte genetiske mutationer, hvor der er behov for at analysere tusindvis af pr\u00f8ver af genetiske oplysninger. <\/p>\n

En karakteristisk egenskab ved det offentliggjorte v\u00e6rkt\u00f8j er muligheden for at skabe programmer til behandling af krypterede data ved hj\u00e6lp af standard udviklingsmetoder p\u00e5 C++. Ved hj\u00e6lp af den leverede transpiler konverteres C++-programmet til en specialdialekt af FHE-C++, der er i stand til at arbejde med krypterede data.
